Excellent for industrial prototyping
We bought ten of these for our lab. The build quality is solid, and the RISC-V architecture handles our complex threading tasks without breaking a sweat.

Best value for dual-band dev
Hard to find affordable boards that support both 2.4 and 5GHz with an external antenna option. This fills that gap perfectly for my smart home gateway.

Easy to get started
As a beginner, I was worried about the setup, but the Arduino IDE support worked out of the box. The USB-C port is a nice modern touch.

Solid range with external antenna
Paired this with a high-gain dipole antenna and the range is impressive through walls. Only minor issue is the heatsink gets warm during continuous transmission.

Perfect for Wi-Fi 6 projects
This board is exactly what I needed for my dual-band IoT project. The external antenna connector makes a huge difference in signal stability compared to onboard antennas.

Great hardware, documentation could be better
The ESP32-C5 chip performs wonderfully with low power consumption. However, finding specific pinout diagrams for the 5GHz configuration took some digging in the forums.
Q: What is the maximum data rate supported on the 5GHz band?
A: The ESP32-C5 supports Wi-Fi 6 features, offering significantly improved throughput and latency over previous generations. In ideal conditions, it can reach speeds up to several hundred Mbps depending on your network environment and antenna setup.
Q: Does this board come with an external antenna included?
A: No, the board features an IPEX/U.FL connector for you to attach your own external antenna, but the antenna itself is sold separately to allow for customization based on your frequency needs.
Q: Can I power this board directly from a 3.7V LiPo battery?
A: While the chip operates at 3.3V, we recommend using the USB-C input or a regulated 5V source connected to the VIN pin. Direct connection to a LiPo battery requires an external LDO regulator to prevent voltage fluctuations from damaging the board.
Q: Is this compatible with the standard ESP-IDF framework?
A: Yes, the ESP32-C5 is fully supported by the latest versions of the ESP-IDF (Espressif IoT Development Framework). Please ensure you are using version 5.0 or higher.
Q: Are there example codes available for Zigbee implementation?
A: Yes, the official GitHub repository contains multiple examples for Zigbee, Thread, and Matter protocols specifically tailored for the C5 series. Check the 'examples/peripherals' folder in the SDK.
